PyOCR is an optical character recognition (OCR) tool wrapper for python. That is, it helps using various OCR tools from a Python program.It has been tested only on GNU/Linux systems. It should also work on similar systems (*BSD, etc). It may or may not work on Windows, MacOSX, etc.

This package contains an OCR engine - libtesseract and a command line program - tesseract. The lead developer is Ray Smith. The maintainer is Zdenko Podobny. For a list of contributors see AUTHORS and GitHub's log of contributors.

This wrapper binds the TessBaseAPI object through ffi-inline (which means it will work on JRuby too) and then proceeds to wrap said API in a more ruby-esque Engine class. To make this library work you need tesseract-ocr and leptonica libraries and headers and a C++ compiler.

You'll need to add language files to help Tesseract recognizing text in the images you feed it. Download version 3.04.00 of the tessdata files here and add your required language to the app/tesseract/tessdata/ folder of your app.

Aristocrat is simple utility that allows you to decode barcodes on your screen and read the text in images and scanned PDFs. After choosing "Capture Screen..." in the Aristocrat menu bar, select an area of your screen (which can be done through a system-wide hotkey) and Aristocrat works its magic.
